紧急避灾通道是煤矿安全生产中最重要的安全措施之一,为了提高救援避灾能力和管理效率,对井下避灾路线进行分析研究。通过分析巷道可通行性及巷道的各影响因素,确定其当量长度;针对预设的避灾路线在灾害发生后被阻断的情况,在Dijkstra算法的基础上,结合煤矿井下实际环境,对其进行改进,改进算法可以动态实现井下最佳避灾路径选择功能,在短时间内计算出从事故发生点到安全地面的最优路径,适合突发事故现场的应用。在改进Dijkstra算法的基础上,笔者设计了一种路径搜索算法,该算法可实现计算从事故发生点到安全地点的N条避灾路线,并在Eclipse中用Java语言设计并验证了这两种算法,证明了它们的正确性和有效性。
Emergency evacuation passage is one of the most important safety measures in coal mine safety production. In order to improve rescue and disaster avoidance ability and management efficiency, the emergency evacuation route is analyzed and studied. Based on Dijkstra’s algorithm, combined with the actual underground coal mine environment, the paper analyzes the feasibility of the roadway and the influence factors of the roadway to determine its equivalence length. In view of the situation of the disaster prevention line being blocked after the disaster, , The improved algorithm can realize the optimal underground disaster avoidance route selection function in a short time and calculate the optimal route from the point of accident occurrence to the safe ground in a short period of time and is suitable for the application of emergency scene. On the basis of improving Dijkstra algorithm, the author designs a path search algorithm that can calculate N avoidance routes from accident occurrence to safe place and design and verify these two in Eclipse by using Java language Algorithm, proved their correctness and effectiveness.
